Answer:

The answer is 9x² - 6x - 1

Step-by-step explanation:

∵ (6x³ + x² - 10x - 1) - (6x³ - 8x² - 4x) =

0 + 9x² - 6x - 1 = 9x² - 6x - 1

Answer:

The result is : $9x^{2} -6x-1$

Step-by-step explanation:

The given terms to be subtracted are ;

$6x^{3}+x^{2} -10x-1$ and

$6x^{3}-8x^{2} -4x$

So, subtracting each term to be more clear we get:

$6x^{3}-6x^{3}=0$

$x^{2} -(-8x^{2} )=x^{2} +8x^{2} =9x^{2}$

$-10x-(-4x)=-10x+4x=-6x$

$-1+0=-1$

So, the answer will be :

$9x^{2} -6x-1$

Mercury metal is poured into a graduated cylinder that holds exactly 22.5mL. The mercury used to fill the cylinder weighs 306.0

aleksklad [387]

Answer:

13.6 g/ml

Step-by-step explanation:

Density is found by mass divided by volume

The mass is 306.0 and the volume is 22.5 ml

density = 306.0/22.5 =13.6 g/ml

We have 3 sig figs which is correct

The perimeter of a standard-sized rectangular rug is 4040 ft. the length is 22 ft longer than the width. find the dimensions.

Nataly_w [17]

L = w+22

2(l+w) = 4040
2(w+22+w) = 4040
2w + 22 = 4040/2 = 2020
2w = 2020-22 = 1998
w = 999ft

l = w+22 = 999+22 = 1021ft
w = 999 ft

Elizabeth has a swimming pool at home. She wants to build a deck all the way around her rectangular swimming pool. The width of

galben [10]

Using the perimeter of a rectangle, it is found that she can make a deck of 122 ft wide.

<h3>What is the perimeter of a rectangle?</h3>

The perimeter of a rectangle of length l and width w is given by:

$P = 2(l + w)$

In this problem:

She has enough wood to build a deck that is 280ft, hence P = 280.

The length is of 10 feet, hence l = 10.

Considering that the deck's width will be added to the actual width of 8 feet, we have that w = 8 + w.

Then:

$P = 2(l + w)$

$280 = 2(10 + 8 + w)$

$36 + 2w = 280$

$2w = 244$

$w = \frac{144}{2}$

$w = 122$

She can make a deck of 122 ft wide.
